OUTSTANDING. Beats e-fax, Kinko's/Fed Ex, all of them buy incomparable margins! Price, customer support, tech/innovation - all of it! The difference of apples and oranges! Keep up the terrific work! Well done.

THIS PROGRAM IS VERY USER FRIENDLY. THE ONLY THING THAT I DONT UNDERSTAND IS THAT WHEN YOU RESAVE THE DOCUMENT IT DOES NOT UPDATE THE TIME OF YOUR MOST RECENT CHANGE.

A great replacement for Photoshop Adobe Acrobat Pro!
I love this tool - I can now replace Photoshop with an affordable option for creating fillable PDFs!

Great for using templates
I work in real estate investment and handle documents and other forms that are basically fill-ins for our tenants. PDF Filler has to make the job 300 times easier because it will add space or make everything look like its in its right space. It makes filling out a document legibly easy and fast so you then can be more productive in your work day.
There are similar programs that allow you to do the same thing it might change spacing, or other aspects of a document.

It works well
Very easy to use and affordable, hasn't ever caused me an issue yet. I would recommend to anyone who needs to constantly convert files like I do

I used this for a work purpose
I used this for a work purpose. It made my task a lot easier. Only needed it as a one off, so cancelled my subscription by contacting them. Fast, efficient customer support.

Super helpful site and people
Super helpful site and people! I had to contact them about a billing issue and they were immediately able to resolve it for me.
2021-06-21
Glad to have it. Wished i didn't have to reset with every entry. It should assume you want the same font until you tell the program to change. Gets tedious to change for every number on the page.

I would love to attend a webinar eventually, but time right now does not allow it. I have been extremely pleased with pdfFiller and recommend it to everyone I know who has to fill out a lot of forms.
Maybe slower than hand writing , but legible which is extremely important. My biggest issue is somehow I have two accounts with other documents saved and do not know how to merge them. That was my problem not realizing i had an account already. Thank yall so much!!!
